Surgeon General and global warming It's as bad as we thought	Joseph Romm	13 Jul 2007	Gristmill
Don't miss this tidbit from Former Surgeon General Richard H. Carmona's Tuesday testimony before Congress: He described attending a meeting of top officials in which the subject of global warming was discussed. The officials concluded that global warming was a liberal cause and dismissed it, he said.'And I said to myself, 'I realize why I've been invited. They want me to discuss the science because they obviously don't understand the science,'' he said. 'I was never i ...

Behind the facade of the Planktos 'Voyage of Recovery' A guest essay from Greenpeace scientists	David Roberts	12 Jul 2007	Gristmill
A while back, after some criticisms of his company on this site, I ran an essay by Russ George, CEO of Planktos, defending his work. What follows is a response to that essay from the UK-based Greenpeace Science Unit. ----- Russ George, CEO of self-professed 'ecorestoration' company Planktos, seems increasingly convinced that opposition to his plans for commercial-scale fertilisation of the oceans with iron results from the activities of 'fringe environment ...

A few random climate thoughts Climate skeptics lose even more credibility	Andrew Dessler	11 Jul 2007	Gristmill
The first half of 2007 is the warmest Jan-June period on record, +0.79°C above the long-term average (from NASA GISS data, via QuarkSoup.net). For those who question the consensus on climate change, see the collection of proconsensus statements at Logical Science (hat tip: Michael Tobis). Just recently, my department (the Dept. of Atmospheric Sciences at Texas A&M University) unanimously adopted a statement endorsing the primary conclusions of the IPCC reports. ...

It's Not the Sun Sun is not causing current global warming, researchers confirm		11 Jul 2007	Daily Grist
It's Not the Sun Sun is not causing current global warming, researchers confirm Attention all ye who think the sun might be a primary cause of climate change, and all ye who know someone who thinks that: No. It's not the sun. Researchers have published a study of the last century of solar activity, finding that the sun's output has actually declined over the last 20 years. (And yes, they did brain ...

The first rule of carbon offsets: No trees A good reason we shouldn't love trees, at least not in this case	Joseph Romm	02 Jul 2007	Gristmill
Everybody loves trees. They are so popular as offsets they even make Wikipedia's definition: When one is unable or unwilling to reduce one's own emissions, Carbon offset is the act of reducing ('offsetting') greenhouse gas emissions elsewhere. A well-known example is the planting of trees to compensate for the greenhouse gas emissions from personal air travel. But does planting trees reduce global warming? Not in most places on the earth. The Carnegie Institution's ...

How we know we're not wrong about climate change A professor of History and Science Studies explains	Andrew Dessler	27 Jun 2007	Gristmill
For those interested in why the scientific community is so certain about climate change, take a look at this presentation and this book chapter, both by Naomi Oreskes. She does a great job explaining how science reaches conclusions, and why we can be pretty sure that humans are indeed warming the climate.

Science: Eh, who cares? Hansen says scientists need lovin', too	Kate Sheppard	26 Jun 2007	Gristmill
NASA climate scientist James Hansen has a new paper out, titled 'How Can We Avert Dangerous Climate Change,' which is actually a slightly-edited version of his testimony before Congress in April. The paper is available online here (PDF), and it's worth checking out, of course. But also interesting is the preamble Hansen included in his email announcing the new paper: President Eisenhower was arguably the last United States President to seek and value advice of scien ...

Scientific hubris? Climate change science questioned	Andrew Dessler	25 Jun 2007	Gristmill
In an op-ed in today's Washington Post, Emily Yoffe asks an interesting question: All this is not to say that it's not getting warmer and that curbing our profligate environmental ways is not a commendable and necessary goal. But perhaps this movement is sowing the seeds of its own destruction -- even as it believes the human species has sown its own. There must be a limit to how many calamitous films, books and television shows we, and our children, can absorb. ...

Hansen keeps sounding the alarm Is anyone listening?	David Roberts	19 Jun 2007	Gristmill
James Hansen has a new paper out, co-authored with six other scientists: "Climate Change and trace gases." It appears in the current issue of the Philosophical Transactions of the Royal Society, and Hansen says: "In my opinion, among our papers this one probably does the best job of making clear that the Earth is getting perilously close to climate changes that could run out of our control." Steve Connor has a writeup in The Independent. Sounds l ...

Should the IPCC be more extreme? Recent report published projecting values of sea-level rise	Andrew Dessler	08 Jun 2007	Gristmill
As anyone who reads my posts knows, I am a big fan of the IPCC reports. They are the best summary of what the scientific community knows about climate change and how confidently we know it. A recent article (subscription required, sorry) in Science suggests that some scientists view the IPCC as overly cautious: In the latest report, its fourth since 1990, the IPCC spoke for scientists in a calm, predictably conservative tone (Science, 9 February, p. 754). It is, ...

NASA chief Griffin stands by his Luddite remarks -- as space agency guts climate science work Unfortunate	Joseph Romm	06 Jun 2007	Gristmill
NASA administrator Michael Griffin offered a lame apology for his denier remarks on climate change. The Associated Press reports that Griffin 'regrets airing his personal views about global warming during a recent radio interview.' That is, he apologized for speaking his mind. Sad. In a related story, the media revealed a recent report on how NASA and the Bush administration are gutting earth observation work crucial to tracking climate change: The Bush adm ...

It's raining in Death Valley Or is that geoengineering at work?	Maywa Montenegro	06 Jun 2007	Gristmill
A new study shows that geoengineering should work. Just not exactly how we imagined:Geoengineering could indeed cool the atmosphere, ecologist Ken Caldeira of the Carnegie Institution in Stanford, California, and colleagues conclude in their new analysis. The team examined the impact of 11 possible projects over the next century using computer simulations and assuming trends in greenhouse-gas emissions will continue unchecked. The good news is such measures would ...

2006: Second most extreme weather ever And yet the media isn't reporting it	Joseph Romm	04 Jun 2007	Gristmill
Global warming has long been predicted to make the weather more extreme. Wouldn't it be great if there were an official government index of extreme weather -- of heat, drought, rainfall, and hurricanes -- that would let us know if the prediction had come true? Well, such an index exists: the National Climatic Data Center's Climate Extremes Index. As the figure shows, the most extreme year by far was 1998; 2006 was the second most extreme, followed closely by ...

Catastrophic warming: Is it too late? Scientists weigh in	Tom Athanasiou	04 Jun 2007	Gristmill
Sorry to post this on the heels of 'Doom and gloom blowback,' but this Daily Kos summary of a new study by Hansen et al is too well done to pass over. And do note that Hansen is trying to accentuate the positive. The original paper, by the way, is called 'Dangerous human-made interference with climate: a GISS modelE study' (PDF). And it's not locked down.

Fred Thompson delivers rational, informed, passionate speech about the need for immediate action to combat global warming	Adam Browning	03 Jun 2007	Gristmill
Just kidding. He's an ass: Some people think that our planet is suffering from a fever. Now scientists are telling us that Mars is experiencing its own planetary warming: Martian warming. It seems scientists have noticed recently that quite a few planets in our solar system seem to be heating up a bit, including Pluto. NASA says the Martian South Pole's 'ice cap' has been shrinking for three summers in a row. Maybe Mars got its fever from earth. If so, I guess ...

Not everyone's a Feynmann Public presentations on global warming -- not as easy as you might think	JMG	01 Jun 2007	Gristmill
So I had an opportunity to go see a free, open-to-the-public talk by Dr. Michael Mann, one of the lead authors for the IPCC, the person most associated with the 'hockey stick' graph of temperature, and a faculty member at Penn State University. His topic: 'Global Climate Change: Past and Present.' A review:All in all, a disappointment. It was almost like an advertisement for Edward Tufte's pamphlet about how PowerPoint fails us. Mann, one of the brains behind Realclimat ...

What is the optimal climate? On the NASA administrator's comments	Andrew Dessler	01 Jun 2007	Gristmill
Michael Griffin is a highly educated guy. He has five Masters degrees (count 'em: aerospace science, electrical engineering, applied physics, business administration, and civil engineering) and a Ph.D. in aerospace engineering (see here). However, his interview on NPR shows that all that book learnin' doesn't mean what he says is intelligent. For a recap of the high points of the interview, see David's post. I'm going to talk in this post about what makes our c ...

NASA administrator says stupid things Hard to believe he's part of the Bush administration!	David Roberts	31 May 2007	Gristmill
Everybody and their cousin has already posted on this, so I won't spend a lot of time on it, but yesterday on NPR, NASA administrator Michael Griffin said some extraordinarily stupid things. To wit: I'm aware that global warming exists. ... Whether that is a longterm concern or not, I can't say. ... ... I am not sure that it is fair to say that it is a problem we must wrestle with. To assume that it is a problem is to assume that the state of Earth's climate t ...

Bunk from Beck Real Climate tears apart another fraudulent presentation from E. G. Beck	Coby Beck	29 May 2007	Gristmill
Over at RealClimate today, they present and debunk another fraudulent reconstruction from German school-teacher-plays-skeptic-scientist E. G. Beck. First it was his groundbreaking (as in stick your head in the sand) work on CO2; now he turns his attention to temperature reconstructions for the past millennium. When bad science still doesn't get the result you want, why not spice it up with a bit of plain and simple fraud?

Scientists and alarmism The 'in it for the money' theory of climate science doesn't pan out	Andrew Dessler	29 May 2007	Gristmill
We have all heard the following argument: in order to get funding for research, the scientific community is forced to produce alarmist predictions of climate change. There's a lot wrong with this argument. But it recently occurred to me that it doesn't even make sense. In the latest IPCC reports, what the scientific community said is that our understanding of climate change is quite good (although not 'settled'). This does nothing to build up research funding. T ...

Yet another must-read by James Hansen On 'scientific reticence' and sea-level rise	Joseph Romm	25 May 2007	Gristmill
Sea level rise of 5 meters in one century? Even if most scientists will not say so publicly, that catastrophe is a real possibility, according to the director of NASA's Goddard Institute Of Space Studies. It may seem like I single Hansen out for recommended reading. But that's only because he: is the nation's top climatologist writes prolifically speaks with unusually bluntness for a scientist has been more right than just about any climat ...

2007: hottest year on record so far Or is it just us?	Joseph Romm	19 May 2007	Gristmill
April may have seemed on the cool side in this country, but globally it was the third warmest on record (and the warmest April ever over land). In fact, the National Climatic Data Center (NCDC) reports that 'globally averaged combined land and sea surface temperature was the warmest on record for January-April year-to-date period.' Drudge reported the April news perversely: 'WARMING ON HOLD? Aprils temperatures were below average ...' April temperature anomalies are s ...

Get Your Vacuum Cleaner Ready Southern Ocean losing ability to soak up carbon dioxide, researchers say		18 May 2007	Daily Grist
Get Your Vacuum Cleaner Ready Southern Ocean losing ability to soak up carbon dioxide, researchers say If you're counting on the seas to soak up excess emissions and get us out of this climate mess, you might need a new plan. Scientists say Antarctica's Southern Ocean, a whopper of a "carbon sink," is losing its ability to absorb more carbon dioxide. The findings, published in the journal Science, suggest ...
